Unsealed natural stones, masonry, and cementitious surfaces are susceptible to erosive forces - particularly those generated through high-pressure washing, which is often implemented in removing deep-set algal, fungal, and lichen growth from such surfaces. This results in unsightly damage to your properties and investments. Avoid these issues by using CaraPro® PURE CLEAN as a pre-treatment to light-pressure washing. To maximize the time, effort, and monies afforded to cleaning, don’t forget to find the right CaraPro® reactive penetrating sealer for your particular surface to maintain that pristine look.
